Which guest appearance are you most psyched for? McHale, according to the caption on this photo, at some point, “demonstrates the word ‘prickly’ with the help of his cactus, pineapple and porcupine pals.” Yes, they look very friendly in this picture. I cannot wait. Sadly, we have no idea what Ferguson is demonstrating in the shot below of him with three chickens, but we love it. We’ve also got a surprisingly dignified portrait of Jeong with Elmo for you as well.

The new season focuses on a STEM curriculum, an acronym for science, technology, engineering and math. A sample sketch, per the press release: “Telly, Elmo and Rosita are playing Shape-O-Bots, robots that transform into shapes to help people. Andy, a guy in need of shapes, played by Andy Samberg, rushes in several times and asks the group to transform into octagons, triangles, pentagons and rhombuses!” I feel like that should involve a leotard, but it probably won’t.
